' SPECIFICATION forming part of Letters Patent No. 789,923, May 16, 1905.v

Application led February 5, 1,903. Serial Ho. 142,035.

To all whom, it may cmwen: Be it known that I, ROBERT LICHLITER, a

' citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useul Lubricator, of which the following is a specification.

The invention relates to improvements in lubricators.

The object of the cient one designed for use on locomotives, engines, and Various kinds of machinery and ada ted to afford a continuous supply of oil to t ie hearings of the desired amount. Y

A further object of the invent-ion is to r0-v vide a lubricatorY of this character w ich will be absolutely reliable and which will indicate the quantity of oil supplied to the bearings and enable the engineer t o ascertain positively if the lubricator is working 'properly and if the amountindicated by the dial or scale is being delivered to the bearings.

The invention also has for its object to pr0' vide a lubricator which will enable a quantity of oil deliveredto the bearings to be ui'ckly changed to ada t the flow of Oil t0 t e requirements of a ocoinotive or other en vine or machine. i

lilith these and other objects in view the invention consists in the construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularlyY pointed out'in the claims hereto appended, it being understood that changes in the form, proportion, and minor details of construction within the scope 'of the claims may be inad without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of thc lubricator constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional view on Athe line 3 3 of Fig. 2. Fig. 4 is a detail sectional view of the ratchet-wheel, illustrating the manner of connecting the same with the pump-operating mechanism.

Like numerals of reference designate cor responding, parts in all the figures of the drawings.

1 designates a reservoir constructea.- `f any suitable material of sufiicient strength t. en.- able the lubricator to be firmly mounted on a suitable support, and the said reservoir, which is preferably rectangular in cross-section, is provided with a cover 2, hinged at the back at 3 and provided at thel front with a suitable catch 4 for holdin it in its closed position. The cover may e mounted in any other desired manner, and the reservoir is provided at vits base with arms or extensions 5, located at the front corners, as l clearly illustrated in Fig. -2 of the drawings, and provided at their outer ends with suitable sockets 6, having upstanding annular 'walls and connected at the bottom with the reservoir by passages or ducts 7. The sockets, which havel interiorly-threaded upper portions 8, are pierced at ,their outer walls' by horizontal passages 9, (see Fig. 9,) which are.

threaded for the reception of cocks or faucets 10 and which are arranged in alinement with the passages or duct-s 7, whereb the 'latter may be readily cleaned should t ey become clogged. The cocks or faucets, which are of the ordinaryconstruction, enable the reservoir 'to be drained when desired, and the are readily removable to permit a suitab e instrument to be introduced into the ducts or passages 7 should the latter become clogged.

The upper threaded portions 8 (see F 1g. 2)

of the soc ets ofthe arms 5 receive the lower ends of upright cylinders 11 of force-pumps, which are exteriorly threaded at the lower ends of the cylinders to fit the said sockets,

ots 16 for conneeting the walking-beam with,

o gers of the force-pumps.

the yokes and the threaded upper ends of the plungers or pistons permit the parts to bead- Justed to vary the length of the said plungers or pistons. tions 13 receive the ends of a walking-beam 15, which is slotted for the receptionvof pivthe yokes or sections of the ist-ons or plun- T e slots permit the necessary lateral pla of the parts incident to the oscillation of t ewalking-beam 15. The walking-beam is centrally ivo'ted onA the reservoir, near the top thereo ,bya horizontal stud 17', which 'may be fixed'to the adjacent wall of the reservoir in any desired manner. The pistons or plungers of the force-pumps are reversely reciprocated by the walkin -bcam, so that there is practically a positive eed of the lubricant to the bearings at all times, irrespective of the position of the plungers or pistons, The plungers or pistons extend through suitable stuffing-boxes at the up tween a seat 19 and a ca 20, whic fits over 'the upper end' of the cy der and which is threa ed to engage the same. The disk 19, which .forms a seat or support forthe packing, is arranged upon a suitable .shoulder formed on ,the interior of the cylinder, as clearlyillustrated in Fig. 3-of the accom anying drawings. Each cylinder is provi ed at one side with an enlar ement 21- and is provided at its bottom Wit an opening, which is interiorly threaded to receive the upper exteriorly-threaded end of an upright valvecasivng 22, roundedat the bottom, as clearlyv shown in Fig. 3, to form a seat for a ball 23. The ball :formsa check-valve, and its move'- ment within the valve-casing is'limited by a horizontal pin 24, located above and spaced Allremains closed on t the oil is forced -out of the ger or piston.

The g outer end of the horizontal bore or passage is 1 normally closed by a plug 27, which is adapted to be readily removed to permit an instrument to be used for cleaning the valve should the passages become' clogged. Within the upright bore orpas'sage 25 is'arran ed a valve f casinU "28, receiving a bali 29 and having a j rounded lower end similar to the valve-casing 22 to form a valve-seat for the' ball; 'The g bottom lof the valve-casing 28 is provided with anopeningfor the passage of the oil, and 8o i branch distributing-pipes 3-1 to casings 28. The' lower branch distributinvipes 31 are provided at their lower ends with anges 32 for engaging the caps or couplings, and the upper en 5 shaped coupling 33,F1g.17, wit a pipe 34, av-

i ling 35 isY-shaped,and ltsup t nected with upper branch istributing pipes i or tubes 36, extending to the Vbearings to be' T-shaped, similar to the lower one, 1f desired. The crotch formed by the u per arms of l the coupling 35 is pierced an threaded for cated centrally within the lower arm of the coupling and arranged at ,the upper end of' 'the intermediate connecting i e or tube 35 and ada ted to separate and) flowing through the distributing-pipes, whereby' a practically-continuous sup ly -o'f oil will be positively delivered to the liearin to pumps. One-of the plungers or pistons is "moving downward'at all times exce t at the instant of reversal of motion of the eam15, and the oilforced'outward by such plunger flow through the upper or outer distributn pipes or tubes. T e lower end or apex the wedge is arranged centrally of the'upper or outer end' of the intermediate connecting pipe or tube and extends entirel across the same, as clearly shown in Fig. 8 o the aocpmpanying drawings. The distributing pipes orV tubes may,l asillustrated in the accompanying drawings, extend to the ba'ck ofthe reservoir or they may be located whollyiiniront of the same, and their upper portions ing acoupling35 at its upper end.

are provided with globe-valves 38* and with l duced to form' a journal and is arranged ina' cocks'or faucets 39, Fig. 2, having nozzles extending inwardly or forwardly over the reserl voir, which is provided in its top with screen covered openings 40, forming strainers and located directly beneath the discharge ends of the cocks or faucets 39 to permit oil to flow from the seam' into the reservoir. By this construction an engineer is enabled to, divert the oil from the bearings and cause the same to discharge through the faucets '39.back into the reservoir in order to ascertain exactly the amount of oil being delivered. to the bearings. By this construction the operator may ascertain accurately whether the feed of the lubricator corresponds. tothe indicator,y and any inaccuracy may be readilyY corrected bythe valves 38a to prevent the vlubricant from discharging or feeding too irregularly. Should there be an)v dill'er'e'nce in the feed or dis charge of the tii'odistrib'uting-pipes, it may be readily lcorrected b v adjustin thevalves 38a. Alsoy thesev valves will ena'le the discharge of thedistributing-pipes to be varied, and should for any reason it be desirable to supply one set obearin'gs with more oil than the other the valves 38a may be adjusted to constrict one ofthe distributin v-pipes and relatively enlarge thepassage o? the other.

The walking-beam is connected by a bar o r pitinan 41 with an adjustable wrist-pin 42, which is adapted to be moved inward and outward toward and from the center of the ratchet-wheel 43 to vary the length of the stroke, and consequently the amount of oil forced through the distributing-pipes by the plungers or pistons. The adJustable pivot or wrist-pin is provided 'with a polygonal body portion 44 of rectangular form arranged in a suitable guide or Way of the ratchetwheelV formed by arallel ribs or flan es 45, as clearly illustrated in F i 4 of the rawinvs. The'ratchetfwheel, whic may be of any desired construct-ion, is preferably' com osed. of inner and outer sections 46 and 47, t e inner section being preferably constructed of steel to form a bearing andthe outer section being preferabl f made of brass or other suit able materia The inner portion of the adjustable pivot or wrist-pin is provided with a`threaded opening 48 for the reception of A anladjusting-screw 49, andl the outer portion of the same is threaded fora nut 50. The intermediate lrtion of the pivot A,or wrist-pin is of two diameters, the smallerportion 51 forming the pivot roper and assing through a perforation of t e lower en of t-he connecting 'bar or pitnian 41. The larger portion 52 is arranged in a slot 53 of a plate 54, arranged between the ribs or flanges 45, as illustrated in Fig. 4 of the drawings-and provided with a scale 56 for indicating the position of the wrisbpin or pivot, and vconseuently the amount of oil fed to the bearings. f lhe inner end 57 of the adj usting-screw is re- -bearingopening of the lugr 5S, formed integral with the outer section of the ratchetwheel, as clearlysliown in Figs. 1 and. 5, and the outer portion or' the adiustiiig-screw is arranged in a bearing 59, having a removable plate adapted to be readily detached to er- "niit the adjusting-screw to bearrang in and removed from its bearings. The adjusting-screw is provided with acollar or flange 60, forming a shoulder for engaging the ciiterbearingand av suitable head havamil-led periphery is arranged at the outer end of the screw to form a grip or han? die. The long threads of the adjustingscrew engage. correspond' G threads of the pivot or wrist-pin and ena le the (pivot or wrist-pin to be quickly adjusted ra ially by a slight rotation of the adjusting-screw, and the feed of the oil changes instantly with the adjustment of the screw. This is highly advantageous', especially in starting a heavy train,'where the movement of the parts are slow and where there is a heavy strain. A large amount of oil may be supplied 'at this time, and the feed may be reduced while the train is running at a high rate of speed, as less oil will then be required. The plate, which is graduated to form a scale, may be secured to the ratchet-wheel in any suit-able manner, and its slot limits the adjustment of the pivot vor wrist-pin and prevents the'pistons or plungers from being reciprccated too far. The inner section 46A of the ratchetwheel is suitably secured, by screws or other suitable fastening devices, to the outer section, and it is provided with a central recess 6l to receive'a head or flange 62 of a stud or stub-shaft 63, upon which the ratchet-wheel rotates. The ratchet-Wheel is also provided Vat its inner section with a central opening communicating with the recess 61 and receives the stub-shaft or stud 63, as clearly ICQ 64. is provided with any desired number of ratchetfteeth to produce the desired rotation, so that the ratchet-'wheel will make one' complete rotation at the end' of the desired' num er of revolutions of the driveshat or eccentricof an engine; but it may be arranged to be operated by and correspond with any other movable portion of an engine or machine, as will be readily understood. The

ratchet-Wheel is engaged by an actuating pawl or do 65 pivoted to the upper portion of an osci ato lever 66, which is provided rio' between its en with an opening for the rel cepti'on of the stub-shaft 63, ii on which the ratchet-wheel is mounted. l actuatin pawl or dog is pivoted tothe upper arm o the lever 6G by a screw 67 and is connected with a spring-68,*wliicli holds the tooth of the paw] o'r dog in engagement with the ratchetwlieel. The lower arm of the lever is provided with a longitudinal slot 69 and is adjiist'ably secured to a reciprocating rod 70 by a screw 71; 'The rcciprocatory rod, or bar 70 is designed to be connected with the eccentric or with any-other movable portion of an engine or machine, and it is provided', adjacent t'o the lever 66, with .a series of perforations 72 for the reception of the screw. The screwnas asmootli portion 73, which forms a pivot and which receives the. actuating roti or bar, and the threaded portionof the vscrew passes through the slot of the lever and is rigidly secured to the sam'e by inner and ,outer nuts 74 and 75. The rod or bar 70 is arranged between the head of the screw andV the inner nut. The screw 67, which forms the pivot of the pawl'or dog 65, is construct- -ed siinilarlv tothe screw 71 just described,

und all of the pivots of the lubricator may bev arranged in a similar manner, if desired.

` The adlustable' connectionbetween the reciprocatim't actuating-barV and the vibratory lever enables the length of the active portion of the' lower end of the lever to be varied to varx` the stroke ofthe upperarm and the consequent movement of the pawl or dog tocause the ratchet-wheel to be advanced the 'ward-i by the actuating n iechanisn'i.

, The reservoir is provided at its top with a pair of pivoted plates or co'vers 76, adapted to be swung overthe screened apertures to exclude dust from the reservoir when` the cocks or faucets of the distributing-pi es are not in use. The reservoir is designe to be provided with asuitable glass sicht-gage 77 to enable the'quantity of oil within theresyervoir to be ascertained.
